Using MB Premium 4.0.4.49/1.0.19344/1.0.823.
Since a few days, the MB tray icon doesn't show when I start up my computer. At first I just opened mbam.exe and then the icon would show but that doesn't work anymore either. I browsed the forum and followed the advise to open Task Manager/Details. The process was not included so I opened mbtray.exe and the icon showed. However, in Task Manager I noticed a few strange settings for the MB components: they were either disabled or not allowed (see screenshot).
That doesn't look right. I also added the mbst-grab-results.

For the second time, all 4 protection modes in Malwarebytes 4 were suddenly disabled. My system was frozen for a minute or so. I did full scans (MB and Defender). I used the Support Tool to collect the logs and also attached a screenshot of an error logged by Windows. I hope the data will reveal the cause.....

Thank you all for the further explanations. Again, I appreciate all the help you offered and apologize again if any of you felt pressured by my posts. I misunderstood whom I was communicating with and felt not heard at certain moments. Luckily, in the end a staff member stepped in and clarified the situation.

@AdvancedSetup Thank you for that acknowledgment, AdvancedSetup, and good to know that you guys are working on a solution. Until then, I'm happy to use version 3.
I didn't know that the moderators are volunteers and not Malwarebytes employees. It would have helped me to know this from the beginning. I appreciate their help and support, and apologize if I made them feel pressured, believing they were employees.
